CVE-2007-5577: Multiple cross-site scripting (XSS) vulnerabilities in Joomla!

Security readout for executives and security teams

Older Joomla! sites before version 1.0.13 contain multiple cross-site scripting flaws. An attacker could inject script or HTML through certain content-management fields, potentially affecting administrators or users who view the injected content. The bundle does not show active exploitation or a CVSS score. Exposure is likely limited to organizations still running Joomla! 1.0.x versions earlier than 1.0.13. Because Joomla! 1.0 is very old, any internet-facing instance should be treated as legacy risk until version and compensating controls are verified. Prioritize if any Joomla! 1.0-era site remains online, especially if it handles customer-facing content or administrator sessions. The age of the platform is the larger operational risk, even though this CVE has no cited active exploitation in the bundle. Mitigation focus: Upgrade affected Joomla! installations to 1.0.13 or later guidance-supported replacements.; Check current Joomla! vendor guidance for legacy migration recommendations.; Restrict administrative access to trusted networks where possible..
